1,085,686. i Application filed March 9,

To all whom t may concern Be it known that I, EBENEZER A. IV. Jnrramas,a. citizen of the United States, residing at Worcester, in thecounty ofVorcester and Commonwealth of Massachusetts, have invented a newl andluseful Improvement in Gas-Producers,fof whichV the following is aspecification, accompanied by a drawing forming a part of the same andrepresenting a. side velevation-of a gas-producer, .shown in centralvertical sectional view" and embodying my present invention.

Referring to the accompanying drawing, 'ldenotes a gas producing chamberand 2 the gas producing chamber. Mounted lupon, the bottom of theash panis a centralair chamber 3 to which air under pressure is suppliedthrough a supply pipe 4. llhrough openings in the top of the chambervavblast of air is delivered tothe interior of the gas producing chamberin order to support comgas producing chamber from a hopper The abovementioned parts of the apparatus form'no part of my present inventionand may be of any known and usual form The lower portion of the casingsurrounding the gas producing chamber consists, preferably, of ametallic wall 6 surrounded by an annular chamber 7 'which-is suppliedwith water in order to prevent the undue heating of the metallic wall 6.In t-he present instance water is supplied to the annular chamber 7 byan overflow pipe 8 leading from a water chamber 9 formed on the cover ofthe gas producer for the purpose of water. sealing the fuel feedingmechanism'. The annular chamber 7 is also provided with an overflow pipe10. A

Inclosed Within the annular chamber 7 is a coil of pipe 11 communicatingat one end, through a pipe 12 wit-h a source of water supply and at theopposite end, in the present instance, through a pipe 13 with a pipe 14passing diametrically through the gas producing chamber 1. The pipe 14is connected with a pipe 15 which enters the air supply pipe 4 andcommunicates with a vertical pipe 16 through which water, heated by itspassage through the coil 1 1 and pipe 14, is delivered int-o the airchamber 3 through nozzles 17, 18 and 19 at the top of the vertical pipe16. The deIiVerythrOugh Specication of Letters Patent.

f In .the construction 37 and 18 are directed 1,910. serial No. 543,172.

the nozzles is, preferably, in the. form of a spray which facilitates athorough admin'.- yture of water with the au.' passing into the PatentedFeb. 3, 1191/11.. i

gasproducing chamber through the suppiy pipe 4. ward through the nozzle19 strikes a cap' or baille-plate 2O and, that portion which falls bylgravity, p-lateQl fronrthe edgeof which water falls downward lmeetingtheupward current of air which lissupplied from any suitable source ofair 'supply under pressure such,` for example, ias a pressure blower, orother means now employed for forcing an air blast into the gas producingchamber.

shown in the present dra-wing, the air chamber 3 communicates withchambers inclosed by the radiating arms 22, 2Q and the nozzles towardthe chambers inelosed by these arms so that the spray of water will bedelivered into each of the chambers, that lodging in the chambers beingconverted into steam and carried out into the gas producing chamber bythe air blast, through slots 28. Y

It has been customary heretofore to ad mit a mingled current of air and.steam through the supply pipe l to the gas producing chamber, the steambeing admitted under pressure in the form of a jet, the force'ofwhichserved to induce an *air current which,

mingling with the steam, was admitted to.

the gas producing chamber' to support cornbustiou. By my presentimprovement force a current of air under pressure through the pipe, andsupply the requisite moisture by vaporizing the water admitted to theair chamber 3, preferably inthe form of a spray, .the water supplyhaving been preheated by heat generated inthe gas producing chamber.

I do not confine myself to the specific constiiuetion shown anddescribed for the purpose of imparting heat to the wat-er supply, *butlI have shown what I deem to kbe a preferable and convenient method ofimparting heat to the water su ply b conductinoa the P s water throughthe coil. of pipe 11, preferably of copper, submerged in the watercontained in the annular water chamber 7, which becomes heated by heatgenerated within the gas producing chamber and conducted through acommonxnetallic wall G. I- thereby "avoid the -extra cost involved inThe' water passing verticallyv up-z of a gas producer, as

is received upon a conical shield Y icc ber, I am able to reduce gvconverting the water into steam by the method now commonly practised,and also 1. In a gas' producer, the combination'` with a gas producingchamber, of a watercooler for a part of said chamber, an air inlet pipefor the admission of air to said chamber, and a Vwater pipe leading froma vsource of wat-er supply to said inlet pipe and' inclosed within saidwater cooler,

whereby the-water in said water pipe is heated by the heat of the waterin said water cooler,

2. In a gas dproducer, the combination with a s pro ucing chamber, of aWater cooler or a part of said chamber, an air inlet pipe for themadmission of air to said chamber, and a water-pipe leadmg from a sourceof water supply to said inlet pipe and passing throng said water cooler.

3. n a gas' with a 'gas pro ucing chamber, of a water cooler for a partof said chamber, an air inlet pipe for the admission of air to saidchamber, and a water pipe passing through reducer, the combinationfammes@ said water cooler and through the'fire in said chamber anddischarging' into said inlet pipe. K

4. In a gas producer, angas producing chamber, an air' inlet -pipe tosaid chamber, an annular water chamber surrounding said gas producingchamber having a common dividing wall, a coil-of pi e inclosed in saidwater chaumber, a pipe eading from one end of saidcoil .to a source ofwater supply, and a pipe leading from the oppositeend of said coil tothe mterior ofvsaid air inlet pipe.

5. In la vgas producer, chamber, an inclosed air chamber, an air supplypipe leading tosaid air chamber, hollow arms extending laterally fromsaid air chamber-into said gas producin cham-v ber and 'having openingsfor the elivery ,of air thereto, means for supplying water to theinterior of said hollow arms, and means for preheating the water supplyby heat generated in the gas producing chamber.`

In a gas producer," .thecombination with a gasproducing chamber, ofanair chamber inclosed in s aid gas producing chamber, means forsupplying air under a .gas producing pressure to said air chamber,hollow arms communicating with said air chamber and extending into saidgas producing chamber and having openings thereinto, and means forlsupplying preheated water in the form of a spray to said air chamber.
